usb: Change transfer_len type to int32_t in usb_request_handler typedef

Browse source 
The functions that implement usb_request_handlers are already using an
int32_t for transfer_len, so lets make the typedef match.  This address
a potential issue in the future when the typedef of int32_t changes (or
when building with newlib).
